We are still looking for someone able to write us a quick SANA-II driver for the ESP8266. It shouldn't be a big job but it requires someone's time. As of today, I can't answer your question on "when" because work on this part hasn't started.

I went online with V500+ with a Plipbox connected on Parallel port. It's actually the easiest way to get online on A500(+). I did it with the Roadshow stack. It was really straight forward. I have to admit it still isn't the best solution as the Plipbox is really slow (40KB/s... versus the 2MB/s we got on A600 with PCMCIA Ethernet and it is a bit unstable...).

Thanks for answering. You can maybe leave a post at the A1k.org Amiga Forum. It's the most famous Amiga Forum in Germany and there are some talented People, who can help out for sure.
You can do it also in English...

I've been very reluctant to purchase any ethernet solution for my A500 after learning of the v2+ expansion for a wifi module. Curious to know the progress and what exact module should I be looking to buy once a driver is ready. Is the ESP8266 what I should get? I really don't want to get a PlipBox only to replace it later. I've received my Vampire A500 v2+ yesterday but haven't installed it just yet because of time.
